Application filed. December 5, 1929.v Serial No. 411,821.

invention relates to a class of machines built for the purpose of wearing in inside and outside'journal bearings on the journal to which they are to beused.

The object of-m-y invention is to provide means in such-a machine that the journal and its hearing are worn while the wheel is in motion wi tl-1 the'-weight on the wheel and the brake cylinder pressure against the journal while the bearing'is being Worninto the,

journal/ r I V v Another object of my invention is to provide means whereby the wheel journal has the same weight and thrust that it will be subjected to in actual service; r

Another object of my invention is to pro c Figure 2 is an end elevation of Figure 1 with a'ear wheel and journal rolled therein. F igure 3 is a top plan view 'of'Fi'g-urefl.

' Figures '4 and 5 respectively are top and end views of the oscillating mechanism; I 1 The referencenumeral 6' designates .a framlng, preferably set in a concrete base 7,

in whichfl also position a wheel track 8 e which, as shown in FigureQ, extends out.- wardlyfrom the frame whereby car wheels ion axles may be rolled from the shop floor into the machine, thereby eliminating separate lifting means. 1 The frame has a for ward-lyl extending top- 9 hollow and'o-f built up construction, 'asshown in Figure 1, there beinga slot 10 in-the bottom. wall ofthis housing. Rollers 11 are journalled in bearings 12 in-thehousing 9 and project, as seen in Figure 1, below the'bottom face of the housing. Preferably there are twoof these 0 rollers 11 in each housing 9, the rollers of.

each pair being so spaced from each other asto insure a proper bearing on the tread of the car wheel 13.

A shelf. 14 extends between the housings 9 and'frames (ion which are mounted two air brake cylinders 15 which are rigidly secured in position. The piston rods 16' of the cylinders are, preferably, forked at their upper ends, and a beam or crossrail '17 is secured in the forked ends'of the rods" 16'.

A hanger; strap 18 is mounted oneach end of the beam 17 to which the upper end of the hanger 18is secured bolts or rivets 19. A stirrup 20 is secured to: the lower end of the hanger 18by bolts or rivets'28 and terminates at' 'its lower end in a forwardly extending housing 21, which is designed to re ceive, and, hold the journal bearing 22'.

Some railroads use on their engine truck wheels inside bearings. To treat these on my machine it is only necessary to place the hangers and their immediately attached parts'in the position shownin dotted lines in Figure 1. e

Extending upwardlyifrom the shelf 14- are guides 2d to provide astop, the desired distance above the beam 17,130 limit the upward movement of said beam. i The frame 6 is provided with a'bracket 25 on which is suitably mounted a suitable mo tor26 eonnectcd'with' a power shaft 27' to which is keyed a pinion 28" which meshes with a gear wheel 29, and this in turn meshes vwith pinion 30 keyed to the shaft31. The rollers 11 are keyed tothese shafts 27 and 31 whereby said-rollers are positively driven.

Thegear wheel 29 is provided with a pinion 32 which in turn meshes with a pinion 33 .lreyed to the stub shaft 3. 1 having a worm 35 formed therein which meshes with a Worm gear 36 carrying a post 37 having on its upper end an eccentric pin 38 which projects intoa, slot 4:201 other openingin the bar 40, which bar is connected to the hangers 18 whereby when the-bar 40 is, oscillated by the eccentric pin38 the hangers are oscillated which, in turn, causes the bearings 22 to oscillate with reference to the journal while the journal is revolving. c

After the wheels are'rolled'from the shop floor or into the machine, as shown in Figure 2, (the bearing 22 being in place) air is admitted into the air cylinders by the two way valve 41 through the pipes 43, where upon the rods 16 are elevated carrying with them the beam 17 and hangers 18 until the treads of the wheels 13 contact with the driving rollers 11, wheels 13 are in the elevated position indicated by the dotted lines in Figure 2. The valve ll is for the purpose of in creasing or dehreasing the pressure-on the journal while the wheels 13 are in motion to, as nearly as possible, obtain the same weight that the wheel will have thrust uponit in ac tual service. The pressure in the cylinders being designated by the gauge 14.

The oscillating mechanism described is designed to oscillate the bearing 22 back and forward on the journal while the wheel 13 is rotating in order that the journal and bearings will have a motion in the machine such as it has in actual service.

As stated, the machine is designed to take careof the inside and the outside bearings.

This machine breaks the journal in prep erly to the brass 22, so that when the journal and brass are placed in actual service the journal will run without heating, thus elimi nating delays and failures on the line of road due to heated bearings. The actual condition of the bearings and ournal can be developed in thismachine before the-journal and bearings are placed in actual road service, thus all corrections are made before the i ournal and bearing are put in service.

The bar 40 is provided with a series of bolt openings 15 at each end. To transmit the reciprocatory movement of the bar 10 to the hangers 18 I secure a block 15' to the bar by means of bolts 46, said block having an elongated opening 47, through which the bolts pass, said elongated opening providing for adjustment of the block 45 relative to its bolts for position to engage the hangers. The block 45 is provided with rearwardly extending arms 18 which. engage and extend on each side of the hangers 18' so that as the bar 40 reciprocates its movement is transmittedthrough the arms48 of the block 47 to the hangers 18.. r

The series of bolt holes 455 permit of read ily positioning the blocks 47 on the bar'LO for adjustment of the hangers 18 to fit various lengths of axles in inside and outside journals. The pin 38 is provided with a bushing 49.

What I claim is:

1. In combination, in a machine for wearing journal bearings on the journals with which they are to be used, a frame, driving rollers on the frame, a wheel supporting carriage vertically adjustably supported in said frame for moving the wheel carrying the journal toward and from the rollers, a journal bearing supporting means carried by said carriage.

2. In combination, in a machine for wearing journal bearings on the journals with which they are to he used, a frame, driving rollers on the frame, a carriage vertically adjustably supported in said frame for moving the wheel carrying the'journal toward and from the rollers, a journal bearing supporting means carried by said carriage, and means to raise and lower said carriage and support the carriage in its adjusted position.
